I use fltk-1.3.x-r7339, linux, X11R7 . My application draws an image into a 'class Canvas: public Fl_Group' that - for a large image - has scrollbars. I use
rgb->draw(clip_x - scroll_x, clip_y - scroll_y); to draw an RGB image. If the image is large, the scrollbars are shown. The scrollbars move. But the image does not SEEM to move. When I overlay the FLTK window with another window and then make the FLTK window the top window again: then and only then the image is shown to have moved. Fl_Image.cxx now sees the GraphicsExpose event. I have made a lot of changes, have used fl_scroll(); no change was able to move the image when the scrollbar moves. Fl_Image.cxx always returns with a width of 0. fltk-2.0 simply moves the contents of the Canvas. But fltk-1.3 is stubborn. What do I make wrong? winfried _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
